other parts below or in front of the roller beam requiring attention.

These and other advantages which, if not hereinafter pointed out, will be obvious to those familiar in this art, are attained or rendered available by my present invention.

The forms of the invention which are the subject of the following detailed specifications, will be understood as taken merely for purposes of illustration of the principle 0 the improvement and o the best way in which I have at the present time, embodied that principle, and will not be regarded as indicating or imposing any limitation upon the scope of the invention.

In the drawings forming a part hereof, Figure l is a cross-section of a roller beam with a thread board mechanism of this invention applied thereto, the thread board rail being also in section; *ig. Qisasimilar view with the thread guide turned up and illustrating its operation; Fig. 3 is a top plan of Fig. l with one of the hinge joints in horizontal section, on line To all whom it may concern:

Be it known that 1, WILLIAM O. ALDRICH, a citizen of the United States, residing at \Vhitinsville, in the county of Worcester and State of Massachusetts, have invented Thread-Boards, of which a full and true specification follows.

The object of the invention is to provide improved means for the support and adjustment of the thread guides and to simplify the construction and number of parts in the thread boards of spinning or twisting machines and to improve the appearance and cleanliness of such mechanism. These results are accomplished, in part, by hinging the wire thread guides directly upon the thread board rail and combining in their hinge connections with the rail, the provisions for their necessary adjustment, whereby the thread guide shanks spring directly from the outer margin of the continuous thread board rail without the interposition of the usual hinged finger-heads, but have provisions for the same lateral and longitudinal adjustment as are found in such finger-head constructions. The results mentioned are further attained by the special arrangement and construction of the hinge joint between the guide wire and the rail, whereby a large'surface bearing is provided for such joint, having the least likelihood of binding or wearing loose, an whereby the adjustment of the thread guide therein may be readily made and securely fixed.

One of the special objects of the invention is the provision of a thread board mechanism which will have a continuous smooth u pper surface extending substantially unbroken from the roller beam close up to the vertical plane of the spindles and forming an effective protecting cover for the parts beneath, shielding them from falling dirt and waste, and which presents no protuberances or crevices to obstruct the cleansing of the thread board, and further to provide a mechanism of this character that is free to be turned back toward the vertical plane of the roller beam, when doffing the spindles, leaving, when thus turned back, a clear open front of the roller beam devoid of projecting apparatus or thread board suports such as might interfere with the work on the spindles or the spindle bands or 33 of that figure; Fig. 4 is a cross-section of a slightly modified thread board and roller beam; Fig. 5 is a top plan thereof, with one joint broken off to a horizontal central section; and Fig. 6 is a further and simplified form.

it will be understood that the roller beam, marked 1 in the above figures, is the usual roller beam or equivalent part on which the rollers of a spinning, twisting or like machine are supported, or above which they are mounted, being a longitudinal member extending the full length of the machine. The yarn from these rollers (which are not shown in the drawings) passes through the guide eyes 2 of the thread board mechanism of this invention to the usual upright spindles (also omitted from the drawings) which are mounted directly beneath them.

It is the object of the thread board mechanism, among other things, to provide supporting means for the guide eyes which will be capable of precise and close adjustment to center them accurately in line with the axes of their spindles. The yarn is spun or twisted in its passage from the rollers to the spindle, and is wound on the latter in the form of thread. hen the spindles are full, the thread board mechanism, of which the guide-eyes are a part, is turned back out o the way in order to permit the removal 0 the bobbin containing the thread.

brackets 5, and it is preferably flush with slotted to receive the shank, which, when in serted, Constitutes the sole means of retain ing the barrel within the knuckle, and the slot in the knuckle extends transversely at least 90 or 100 degrees of its circumference The thread board of this invention coni= prises a thread board rail 3, preferably made of a flat metallic plate, and mounted in hinged relation to the roller beam, by means of the hinges 4, which are disposed at intervals along its length. The thread board rail or plate is continuous with the roller beam, as indicated in Figs. 3 and 5, being closely hinged thereto so that there is no appreciable space or crevice between them when the rail is in its operative, that is to say, its horizontal, position, in which position it is suitably supported, as by means of the small right position. The slot may, however, extend entirely through the knuckle, or it may be of such length (which form is preferred) that its end or ends will serve as an abutment or stop to limit the downward move ment of the guide and hold it in horizontal position. In the form of Figs. 1 to 3, this means of stopping the thread guide is the sole means employed for that purpose. It will be observed that the knuckle in this form is situated within the outer margin of the thread-board rail and that the latter is slotted, as shown at 13, to accommodate the 35 thread guide when turned up (Fig. 2). In this form the entire hinge and guideadjusting mechanism is sheltered by the rail itself, and is thus most easily kept in a'cleanly condition.

'Inthe form of thread board shown in *igs. 4: and 5, the hinge knuckle 14 supports or confines the same pintle barrel 10 with the same longitudinal or axial set screw 11, and may also support the same kind of 5 wire thread guide, having a shank 12, but the said knuckle 14 is formed of a blank the top of the roller beam, or nearly so, when in this position. Its primary function is to form the support or a plurality of the guide-eyes, whereby all or a section of them may simultaneously be turned back toward the vertical plane of the roller.

The outer margin of the thread board rail is supplied with a plurality of hinge knuckles suitably arranged to support each of the thread guides in properly spaced relation with respect to the spindles. These knuckles may be formed integrally with the rail by curling the ct go of it, as indicated adjustment of position thereon. In Figs. 1 to 5, the knuckles are thus made.

In Figs. 1 to 3 the knuckles are marked 7 and are formed from a flat blank rolled or curled into tubular form at one end, with the other end left flat and forming the attachment leaf 8, which is provided with two bolt-holes. The leaf is secured to the under the thread board rails so that the knuckle "side of the thread board rail s that th i 16 which is somewhat oifset from the line f th k kl i b l th l l th f of the thread guide shank to allow the lattheir bolt-holes rather loosely so that the other lGS 0f adjustably attaching the knuckle is capabl f adj t t ith knuckles to the rail w ll meet the purposes spect to the rail. The knuckle 7 forms the 0f thls lnventlon, p o ided h y po he support of a rotary cylindrical block or adequate Strength and sechrlty; T 37x15 arrel 10 which is confined th i d of the knuckle 14 more nearly coincides with serves as the pintle of the joint between the the plane of the Fall, so t the Inward guide and rail. Th bar l i f bl f tremity of the thread guide shaft-that end less length than the knuckle and is placed 0 1t whlch p p l c b yo d e h nge axis centrally therein so as to be protected as may abut against the under side of the rail much as possible from accumulations of dirt 111 o de to ho d he guide in its horizontal and waste, and is also cross-perforated d, posit on, and such abutment means may be further, provided with a l ngit di l used n connection with the abutment means axial bore, internally threaded and adapted dQSCPIhB-Cl f g 1 t0 f CleSlreClh to receive a set-screw 11, the head of which PP I end of the Slot 111 the knuckle/allow projects beyond the open end of the tubular ver, is preferably so located (see 11, Fig, 5) support or knuckle so as to be accessible. h t 11 1 h g' 1 1 a nearly V rtical e guide-eye 2, which may be the usual po ition, when turned up, and so prevents wire pig-tail or any other form of guidethe inner end of the shank from pro ecting eye,'has a shank 12 which is received and utwardly ow r h Spindl slongitudinally adjustable within the cross- Coming now to the form of the invention perforation of the barrel, as indicated, be illustrated in Fig. 6, in wh ch the knuckles ing secured in place therein by the set screw 6 are formed 1ntegrally with the rail, as 1 in the obvious manner. The knuckle is above stated, the thread guide shanks 12 intersect these knuckles, as in the case of all the receding forms, and are pivotally supported therein by the samepintle barrel 10,

in which it is also longitudinally adjustable, but there is no provision for lateral adjustment of the guide-eye in this form, it being intended that the operator will use his pliers to bend the shank as needed and as is done in the case of wooden finger-heads and preferred by many. The axes of these integral knuckles may be disposed as shown in Fig. 6, so that the inner end of the shank will find an abutment against the under side of the rail, for holding it horizontal, and the upper end of the shank-slot is preferably disposed as in Fig. 5 so as to stop the shank in its vertical position and thus keep the inner end from projecting outwardly beyond the rail. This position is indicated in Fig. 6 by dotted lines.

I claim:
